Adipex (generic name: phentermine) is a prescription medication used as a short-term appetite suppressant to aid in weight loss. It works by stimulating the release of certain brain chemicals that help reduce hunger. Adipex is typically prescribed for individuals who are overweight or obese and have not been able to lose weight through diet and exercise alone. It is intended for short-term use (a few weeks) due to its potential for side effects and dependence. It should be used alongside a healthy diet and exercise program under the supervision of a healthcare provider.
